From: Miaoqian Lin <linmq006@gmail.com> stable inclusion from stable-v5.10.127 commit 44a5b3a073e5aaa5720929dba95b2725eb32bb65 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5XDDK Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 7c7ff68daa93d8c4cdea482da4f2429c0398fcde upstream. of_find_compatible_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.
